Wire Gauge Size Carbide Round-Shank Reamers
These reamers are solid carbide for exceptional wear resistance and high accuracy in addition to excellent abrasion and heat resistance when cutting hard and abrasive materials. They require rigid tool holding to prevent breakage and are not for use with hand-held tools. The shank diameter is slightly smaller than the reamer diameter.

Round-Shank Drill Reamers
Drill and finish holes in a single pass with these dual-purpose tools. The tapered tip gradually pierces your material to reduce friction, and the straight flutes make clean cuts without chipping or peeling the edge of the hole. Made from solid carbide, these drill reamers are strong and heat resistant. The flutes stay sharp even when cutting abrasive materials such as fiberglass, carbon fiber, and graphite. Use them in drill presses or other machines—carbide is brittle, and will break if used to drill by hand.
